Product introduction :

Borax decahydrate is a chemical substance with a molecular formula of Na2B4O7·10H2O. It a semitransparent colorless crystal or crystalline white powder; odorless, salty in taste; loses all crystalline water at 350-400℃ to becomehydrous Borax. (Na2B4O7), density 1.72g/cm3; soluble in water, also soluble in glyol, insoluble in alcohol. Its aqueous solution is weakly alkaline, and it is a colorless glass-like when melted. It has a bactericidal effect and is harmful to human body when taken orally. In terms of chemical composition, it is sodium tetraborate with 10 water molecules. Its crystals are plate-like or columnar, and the crystals are aggregated together to form crystal clusters, granular, porous lumps, etc., with a color of white with gray or light-colored yellow, blue, green, etc., and a glassy luster.

Borax (Na₂B₄O₇·10H₂O) common application scenarios include glass manufacturing, ceramic production, metallurgy, detergents, pharmaceuticals, agriculture, and laboratories, etc. The following are specific applications of borax in different fields:

Industrial manufacturing: Used in production of glass, ceramic glazes, and enamel products, it can enhance the performance and quality of materials. Detergent: Used as a degreaser, softener, and metal surface cleaner, it has certain surface activity and can be used as a detergent, especially effective in removing oil. Medical use: It has certaininfection and anti-fungal effects, and can be used to make eyewash, oral disinfectant (but not for internal use), but use must strictly follow the regulations.
